Then retrieve all tables of the selected database
and finally retrieve all data from the selected table (This i know)
How do i accomplish the above two.

Hello,
i am getting a hard time in minimizing time for data retrieval, over SQL Server DataBase. My DataBase consist of 2 tables. One of the table has more than 10000 entries and other table with more than 10 million entries. I have used SQLNative Client for connecting to data base and my goal was to find a value from the 1st table and search it out in 2nd table. The result is more than hundered thousand rows. Now the problem is: the time it took for retrieving those rows is much slower approx. 12 minutes. Can this time be cut down. I have used SQLClient connection to make sure it is accessing SQL server on a direct access base.
Also, i am using
SqlClient::SqlDataReader
for reading, getting rows returned by the my query.
Please help me out.
Thanx.

i m having a huge problem! how to retrieve data from notepad files using asp.net and store the info in fields in MS-Access/Sql db? Plz help !!

string commandString = "SELECT Id,Name FROM [DatabaseTable];";
using (SqlConnection conn = new SqlConnection(connectionString))

SqlCommand cmd = new SqlCommand(commandString, conn);
conn.Open();
IDataReader rdr = cmd.ExecuteReader();
IList ids = new List();
IList names = new List();
while (rdr.Read())

ids.Add((int)rdr[0]);
names.Add((String)rdr[1]);
}
rdr.Close()

What i want to know is if there is any better way of obtaining the 'id' and 'name' data
values then just assuming that id is the first returned object and name is the second returned object in each reader record.
ie. Is there any way to retrieve a specific field from the reader in a Dictionary-type manner...?

Hi,
I'm using ASP.NET 1.1, SQL Server 2000 Server:
I followed the ASP.NET 1.1 Starter Kit's Commerce application and applied the same principles it had written the code to retrieve data to my web application I created. For example I've written this Function in a class to return a sqldatareader:
Public Function GetAdvanceSearch(ByVal s As String, ByVal Ext As Integer, ByVal fdate As DateTime, ByVal tdate As DateTime) As SqlDataReader
Dim oDrAdSearch As SqlDataReaderDim oCmdGetSearch As New SqlCommand("spAdvanceSearch", oComConn)
With oCmdGetSearch .CommandType = CommandType.StoredProcedure .Parameters.Add(New SqlParameter("@DialNo", SqlDbType.VarChar)).Value = s .Parameters.Add(New SqlParameter("@FDate", SqlDbType.DateTime)).Value = fdate .Parameters.Add(New SqlParameter("@TDate", SqlDbType.DateTime)).Value = tdate .Parameters.Add(New SqlParameter("@Ext", SqlDbType.Int)).Value = ExtEnd With
oComConn.Open()oDrAdSearch = oCmdGetSearch.ExecuteReader(CommandBehavior.CloseConnection)
If oDrAdSearch.HasRows Then Return oDrAdSearchElse Return NothingEnd If
End Function
And When I'm calling this function I do write in this way (assuming that this function is in a class called "Calls"):
Dim objCalls as New Calls
DataGrid1.DataSource = objCalls.GetAdvanceSearch(<PARAMS.......>)DataGrid1.Databind
My application is a Telephone Call Recording System and could expect vast amount of data. Averagely, a month may produce approximately 50,000 records or more. So while querying through my web application for a month, the application itself either gets stuck or the retrieval speed gets drastically slow. However I'm using Datareaders for every querying scenario. My Web application is hosted in a Windows 2000 Server and accessed via Local Network or IntraNet.
What are the ways I could make this retrieval more speedier and efficient? I would like to hear from anyone who have come across this problem and anyone who could help me on this.
Thanks in Advance. Looking forward for a reply from some one.
Is there a stored proceduire that grabs all the data from a specified table and places it in a file.
View 1 Replies View RelatedHello all,
I'm stumped on how to solve this question so I figured i'd ask the community. As a warning i'm not sure best how to describe my situation so i'll try and give as much detail as I can.
First in table A, I have two columns that already have data in them that are numeric (Col1, Col2). Also, in table A I have two more columns that are going to derive their data based of a complicated data retrieveal routine (Col3, Col4). So my table structure looks something like this:
Code:
Table A
Col1 Col2 Col3 Col4
20 20 NULL NULL
(Where Col3, and Col4 are going to be populated based off the routine)
The Data for Col3 and Col4 is in an excel spreadsheet that i'd like to convert into a table for MSSQL. However i'm not sure how to do this because in the spreadsheet there is a lookup routine (that i'm trying to copy to MSSQL code, i'll show that in a minute) that generates its values based off data in the X / Y columns, so something like this:
Code:
_|1__|2___|3__
0|0 |0 |0
1|1 |15 |25
So when 2 is met, and 1 is met, they would equal '15'. No arithmetic involved, just simply matching up the X / Y and pulling the data.
My question is, how do I create tables out of this, so my lookup routines can get the values as a result of matching X / Y? (2, 1 = 15)???
The excel routine is this:
=IF(VLOOKUP(F66,'Appendix A'!A5:K56,MATCH(F68,'Appendix A'!A4:K4,1),TRUE)>F46/12*0.125,F46/12*0.125,(VLOOKUP(F66,'Appendix A'!A5:K56,MATCH(F68,'Appendix A'!A4:K4,1),TRUE)))
Thanks!
Hi All,
I am working on an application to retrieve data to the windows ce 3.0 handheld from the Sql server database. I am able to retrieve the data from the server using RDA pull method and able to see the data on the local handheld database. To display the retrieved data in the dialog to the user, it requires to query the local databse and get the information and then display the information, which is taking some time.
My question is, to reduce the time and improve the performance , instead of pulling the data to the local table, is there any way to pull the data and have it in memory and display the details to the user?
To develop the above application, I used some of the code to pull the data from the server from the sample application C:Program FilesMicrosoft SQL Server CE 2.0SampleseVCeVCReplRdaHPC. I am developing the application for windows ce 3.0 device using eVC 3.0
thanks

Do you have any idea how i can do it or am I approaching it in the wrong way????

A call to a stored procedure completes in 13 seconds when ran from within SQL Server Management Studio. A report whose data source uses the same stored procedure can take as long as 10 minutes to run. The same parameter values are used in both the direct call and the report. The execution log says almost all of that time is spent on data retrieval. How could that be? What might be the cause?

Hi there,
I was wondering if someone could propose a solution for the following scenario:
TimeID column would have values from 1 to 6 and rows will be inserted only for those timeIDs where we have Data value as well. While retrieving data we would like to have all timeID range returned with explicitly specifying NULL for missing Data column. Please see below to better understand the situation.
create table test
(
TimeID INT,
Data INT
)
INSERT INTO test VALUES(1, 100)
INSERT INTO test VALUES(2, 180)
INSERT INTO test VALUES(4, 550)
INSERT INTO test VALUES(6, 120)
select * from test
1 100
2 180
4 550
6 120
Desired resultset
1 100
2 180
3 NULL
4 550
5 NULL
6 120
...

Hi,I wonder if anyone can help with the following on a fee paying basisfor the the design or development of some type of script or utility orpiece of code to do the following work.I wish to retrieve some data from an online database that is in thepublic domain. The online database has a search facility that matchesthe entry (name) in a search box then returns a screen stating that amatch has been found or not found.If a match is found there is a button to click that proceeds to thescreen containing the data which is simply two names. It is these twonames that I wish to retrieve and store them in something like a textfile where they are associated with the original entry (name) used inthe search box.I have a list of the entries for the search box that can be suppliedin sample format for testing as a columnar text file or commadelimited file or a spreadsheet.. I would need the procedure toprocess the list of search entries, retrieve the data then move on tothe next one in the list. Obviously, if a match was not found then theprocess would need to move on the the next entry in the list withperhaps a message saying "No Match" until the entire list wasprocessed.The PC I hope to run the process on is a Windows XP machine and if Ineed to purchase any particular software that is necessary for the jobthen I am quite willing to do so. Also, as I pointed out above I wouldpay for the work to be done.I hope that I have explained the above OK and that I have posted it tothe correct newsgroup(s). If it is not in the correct newsgroup Iwould be grateful if anyone could point me in the right direction.RegardsDave Gibson

I am trying to create a report with a sub report in Sql Server 2012 using Report Builder Version 3. Â I can run the subreport without any problems. Â I read where using a shared connection can cause this error so both the main report and the subreport use a connection that is embedded in my report. Â
For testing, I created the subreport without a parameter and added it to the main report. Â When I ran it that way, the report worked and sub report displayed the data. Â So I know it can read from the database.It seems to only give me this error when I am trying to tie the two reports together using a parameter. Â
Hello Everybody,
I have a small tricky problem here...need help of all you experts.
Let me explain in detail. I have three tables
1. Emp Table: Columns-> EMPID and DeptID
2. Dept Table: Columns-> DeptName and DeptID
3. Team table : Columns -> Date, EmpID1, EmpID2, DeptNo.
There is a stored procedure which runs every day, and for "EVERY" deptID that exists in the dept table, selects two employee from emp table and puts them in the team table. Now assuming that there are several thousands of departments in the dept table, the amount of data entered in Team table is tremendous every day.
If I continue to run the stored proc for 1 month, the team table will have lots of rows in it and I have to retain all the records.
The real problem is when I want to retrive data for a employee(empid1 or empid2) from Team table and view the related details like date, deptno and empid1 or empid2 from emp table.
HOw do we optimise the data retrieval and storage for the table Team. I cannot use partitions as I have SQL server 2005 standard edition.
Please help me to optimize the query and data retrieval time from Team table.
Thanks,
Ganesh
I have a table of vehicle usage records with fields including vehicle number, driver, date/time, starting odo, ending odo. I'm looking to compare the starting odo of a given record to the ending odo of the last time that vehicle was used. I also need to return other fields from that previous record, like the date/time and driver.My users basically run a report for any given day, and the vehicles used on that day need to be compared to their most recent usage (most recent relative to the record at hand). This is to ensure that the vehicle hasn't been used in the interim and not recorded (which may indicate theft).I've got a very convoluted process in place, but I'd like to see if it can be streamlined. The current process is done in Access and has a number of queries built on other queries. It is very slow. The data is in SQL Server. Any thoughts on the best ways to accomplish this?TIA
View 4 Replies View RelatedHi there,
Is there a way to retrieve the set of primary keys from an inserted record, especially when the primary keys are generated upon insertion (ex. identity, uniqueid)? Basically I need to get the ID of the record I just inserted so that I can use it as a reference to that record in other places.
I'm using MS SQL and raw SQL commands (ie. no database interfacing objects). I'm hoping I can tag some sort of SELECT statement on the end of the INSERT command that will give me the results that I need.
Thanks!
Hi all, I dont know if anyone here can help me...I am using ASP.NEt with VB.Net and SQL Sever...What I am trying to do is create a system whereby it allows users to upload images into sql server, and thereon later retireve this image.I used a book called The Ultimate VB.Net and ASP.Net Code Book, and it basically gave me the code below to upload and retrieve images. I seem to have managed to allow the uploading of images, with them being stored as <byte> in my database, thought I have no idea how to retrieve them...Does anyone have any ideas???Here is the code I followed.. :"Storing Uploaded Files in Your Database First, a few tips on storing files inside your SQL Server database.For convenience, you’ll really need to store at least three bits of information about your file to get it out in the same shape as you put it in. I’d suggest “data� (a field that will hold your actual file as a byte array, data type “image�), “type� (a field to hold details of the type of file it is, data type “varchar�), and “length� (a field to hold the length in bytes of your file, data type “int�). I’d also recommend “downloadName�, a field to hold the name that the file had when it was uploaded, data type “varchar�. This helps suggest a name should the file be downloaded again via the Web.The problem you have is translating the information from the File Field control into an acceptable format for your database. For a start, you need to get your file into a byte array to store it in an image field. You also need to extract the file type, length, and the download name. Once you have this, set your fields to these values using regular ADO.NET code.So, how do you get this information? It’s simple: just use the following ready-to-run code snippets, passing in your File Field control as an argument. Each function will return just the information you want to feed straight into your database, from a byte array for the image field to a string for the file type.Public Function GetByteArrayFromFileField( _ ByVal FileField As System.Web.UI.HtmlControls.HtmlInputFile) _ As Byte() ' Returns a byte array from the passed ' file field controls file Dim intFileLength As Integer, bytData() As Byte Dim objStream As System.IO.Stream If FileFieldSelected(FileField) Then intFileLength = FileField.PostedFile.ContentLength ReDim bytData(intFileLength) objStream = FileField.PostedFile.InputStream objStream.Read(bytData, 0, intFileLength) Return bytData End If End Function Public Function FileFieldType(ByVal FileField As _ System.Web.UI.HtmlControls.HtmlInputFile) As String ' Returns the type of the posted file If Not FileField.PostedFile Is Nothing Then _ Return FileField.PostedFile.ContentType End Function Public Function FileFieldLength(ByVal FileField As _ System.Web.UI.HtmlControls.HtmlInputFile) As Integer ' Returns the length of the posted file If Not FileField.PostedFile Is Nothing Then _ Return FileField.PostedFile.ContentLength End Function Public Function FileFieldFilename(ByVal FileField As _ System.Web.UI.HtmlControls.HtmlInputFile) As String ' Returns the core filename of the posted file If Not FileField.PostedFile Is Nothing Then _ Return Replace(FileField.PostedFile.FileName, _ StrReverse(Mid(StrReverse(FileField.PostedFile.FileName), _ InStr(1, StrReverse(FileField.PostedFile.FileName), ""))), "") End Function Sorted! One question remains, however. Once you’ve got a file inside a database, how do you serve it back up to a user? First, get the data back out of SQL Server using regular ADO.NET code. After that? Well, here’s a handy function that’ll do all the hard work for you. Simply pass the data from your table fields and hey presto:Public Sub DeliverFile(ByVal Page As System.Web.UI.Page, _ ByVal Data() As Byte, ByVal Type As String, _ ByVal Length As Integer, _ Optional ByVal DownloadFileName As String = "") ' Delivers a file, such as an image or PDF file, ' back through the Response object ' Sample usage from within an ASP.NET page: ' - DeliverFile(Me, bytFile(), strType, intLength, "MyImage.bmp") With Page.Response .Clear() .ContentType = Type If DownloadFileName <> "" Then Page.Response.AddHeader("content-disposition", _ "filename=" & DownloadFileName) End If .OutputStream.Write(Data, 0, Length) .End() End With End Sub Simply pass your byte array, file type, and length, and it’ll send it straight down to your surfer. If it’s an image, it’ll be displayed in the browser window. If it’s a regular file, you’ll be prompted for download.If it’s made available for download, this function also allows you to specify a suggested download file name, a technique that many ASP.NET developers spend weeks trying to figure out. Easy! Working with Uploaded Images Whether you’re building the simplest of photo album Web sites or a fully fledged content management system, the ability to work with uploaded images is a vital one, and with ASP.NET, it’s a real doddle.The following code snippet shows you how, by example. It takes a data stream from the File Field control and converts it into an image object, adding simple error handling should the uploaded file not actually be an image. The code then uses this image object to extract a few core details about the file, from its dimensions to file type:' Get data into image format Dim objStream As System.IO.Stream = _ MyFileField.PostedFile.InputStream Dim objImage As System.Drawing.Image Try ' Get the image stream objImage = System.Drawing.Image.FromStream(objStream) Catch ' This is not an image, exit the method (presuming code is in one!) Exit Sub End Try ' Filename Dim strOriginalFilename As String = MyFileField.PostedFile.FileName ' Type of image Dim strImageType If objImage.RawFormat.Equals(objImage.RawFormat.Gif) Then strImageType = "This is a GIF image" ElseIf objImage.RawFormat.Equals(objImage.RawFormat.Bmp) Then strImageType = "This is a Bitmap image" ElseIf objImage.RawFormat.Equals(objImage.RawFormat.Jpeg) Then strImageType = "This is a JPEG image" ElseIf objImage.RawFormat.Equals(objImage.RawFormat.Icon) Then strImageType = "This is an icon file" ElseIf objImage.RawFormat.Equals(objImage.RawFormat.Tiff) Then strImageType = "This is a TIFF file" Else strImageType = "Other" End If ' Dimensions Dim strDimensions As String strDimensions = "Width in pixels: " & objImage.Width & _ ", Height in pixels: " & objImage.Height ' Send raw output to browser Response.Clear() Response.Write(strOriginalFilename & "<p>" & strImageType & _ "<p>" & strDimensions) Response.End() "For some reason the retrieval code isnt working for me..Can anyone provide any help? even if it means using another method?

Hi,I am using MS Access as the front end and it's using ODBC link to connectto the backend tables residing at SQL SERVER.I have some queries that are doing some calculation and the time taken toretrieve the data has been quite slow.The no of data in that table is around 500K records. and the tables havealready got the PKs defined.How can i improve the performance of the query besides converting to SQLViews or SP(this is going to be diffcult as i am getting some filterparameters from the forms in MS Access) ?Or what further checks shld i be doing to find out the cause. I have donePerformance Monitor and the CPU processing% is around 20 - 55% while runningthose querieskindly advisetks & rdgs--Message posted via SQLMonster.comhttp://www.sqlmonster.com/Uwe/Forum...eneral/200511/1

I face following problem by last few day, please help me for the same
My Mssql server 2000 with service pack 3 use for my lan bas users, normally they can work fine without any problem, but some time user not able to retrieve information from server. I had debugged this problem and found one small table with 50/60 records not retrieving for so long at clients machine. I open enterprise manage and trough that try to open table, but server in try mode only not show a single row after long time and give message client time out.
I open query analyzer and try to select * from table_name, it is also not retrieve a single row after long time and nothing got as a message.
Shutdown the server and restart , I am able to retrieve that table from EM, Query analyzer and from application also.
I don’t understand what is the problem.
Thanks
R.Mall
Is there any short way to make the server give out IDs of all clientprocesses connected to a specified DB? I guess this information mustbe stored somewhere in system databases...
View 1 Replies View Related[MS SQL Server 7]We load a table from a text file using Data Transformation Services. Thesource file is already sorted by primary key order.After the DTS load, the default retrieval order on the target table (select* from targettable) appears to be random. I know that theoretically theretrieval order from a SELECT statement isn't guaranteed, but this is thefirst time that I've actually had a default retrieval not follow theprimary key order in the table. I'm thinking that what we're seeing is thephysical storage order of the rows in the table, which have been somewhatscrambled by the way that DTS loads a text file (probably some I/Ooptimization).Is there any way that we can get DTS to load the table in the order thatthe rows appear in the text file (assuming that's what our problem is)?The Project Lead really doesn't like the fact that the default retrievalorder isn't following the primary key.Regards,Lyle H.

Hi, All
Can you add a group of images into the aspnet_profile table as a serialized binary blob?
If so how do you retrieve the image from the blob?
Can somebody pls guide me on how i can Store & Retrieve Encrypted Username and Password Hashes.
I want to know following :-
1. I'm doing all the encryption and calculating password hashes on client side (VB), which i want to store in SQL Database when a new user account is created. I want to know what data types to use in Database. I will prefer not to use strings at all on client side due to secruity issues, i want to do all transfer in bytes -> to and from SQL server. How i can do that
2. How the connections can be made encrypted or more secure when doing these communcations.
3. I want to know if this is the right approach or to use the built in features of SQL Server 2005, main reason for not using that is that not all Encryption and Cryptography are supported...
pls help me on this as i'm fairly new to this.
where including/excluding a single column in an empty staging table would influence a resultset returning from distributed query? Both servers are SQL Server 2012. Nothing special about the staging table. It contains 12 columns with a mixture of INT and NVARCHAR(256) columns. In one case I exclude the column and the query returns in 17 seconds. When I include it the query does not return. Excluding the INSERT INTO the staging table and query returns in 17 secs with and without the column.
View 3 Replies View RelatedI have a requirement to implement CDC for 50+ tables to implement incremental data changes warehouse/reporting rather than exporting the whole table data. The largest table is having more than half a billion records.
The warehouse use a daily copy of OLTP db (daily DB refresh). How can I accomplish this. Is there a downside in implementing CDC just for the sake of taking incremental changes on the tables?
Is there any performance impact if we enable CDC on OLTP db?
Can we make use of the CDC tables on the environment we do daily db refresh so that the queries don't hit OLTP database?
What is the best way to implement CDC to take incremental changes for reporting.
is there a step by step paper to get there? here is what i need to consider. I Iwill have many customers that will need their own set of records and access pages "branded for their company" each customer will have many clients. I am hosting this application on a windows 2003 server with SQL 2005 server enterprise.
I am using windows authentication, I have created a username in windows, then i added the windows user in SQL management studio in security, granted "DB Read" and "DB write" and again under the database security tab. still from the web authentication fails. i must be nissing a step or two?
I expect to set up a username for each database as i setup new customers.
Hello,
I am wondering what conversion rules apply, when a string, which contains a number, is saved to a SQL Server 2005 into a column of type decimal.
This is the code I€™m using (C++):
CString cValue = "0.75"
_variant_t vtFieldValue;
vtFieldValue = _variant_t(cValue)
pRecordSet->Fields->Item["MyColumn"]->Value = vtFieldValue;
"pRecordSet" is an ADO recordset. The database column "MyColumn" is of type "decimal(19,10)".
The most important question for me is, if the regional settings of the database server or the regional settings of the client PC are considered during the conversion from the string to the decimal value. For example in standard French regional settings the "." would not be recognized as decimal separator.
I am also wondering if the language of the database instance, in which this data is saved, is considered during this conversion or any other settings of this database instance.
So my general question is: Does anybody know exactly what rules apply during the above mentioned conversion?
Thank you for your help.
Regards,
Volker
